C MAL: cascaded network-guided class-balanced multi-prototype auxiliary learning for source-free domain adaptive medical image segmentation.

Source-free domain adaptation (SFDA) has become crucial in medical image analysis, enabling the adaptation of source models across diverse datasets without labeled target domain images. Self-training, a popular SFDA approach, iteratively refines self-generated pseudo-labels using unlabeled target domain data to adapt a pre-trained model from the source domain. However, it often faces model instability due to incorrect pseudo-label accumulation and foreground-background class imbalance.

First case report of effective and safe application of cannabidiol to treat concurrent ALG3-CDG and Lennox-Gastaut Syndrome.

This study presents the first reported case of a Korean patient with Alpha-1,3-Mannosyltransferase-Congenital Disorder of Glycosylation (ALG3-CDG), characterized by a novel maternally inherited missense mutation and a previously reported paternally inherited nonsense mutation. The patient exhibited typical ALG3-CDG manifestations, including developmental delays, epilepsy, and multisystem involvement, alongside a diagnosis of Lennox-Gastaut Syndrome (LGS). Cannabidiol therapy, combined with dietary management, led to seizure freedom for over 13 months, significant EEG improvement, and enhanced developmental outcomes.

Sympathetic nerve signaling rewires the tumor microenvironment: a shift in "microenvironmental-ity".

Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.

Highly Efficient and Stable CsPbI Perovskite Quantum Dots Light-Emitting Diodes Through Synergistic Effect of Halide-Rich Modulation and Lattice Repair.

Currently, CsPbI quantum dots (QDs) based light-emitting diodes (LEDs) are not well suited for achieving high efficiency and operational stability due to the binary-precursor method and purification process, which often results in the nonstoichiometric ratio of Cs/Pb/I. This imbalance leads to amounts of iodine vacancies, inducing severe non-radiative recombination processes and phase transitions of QDs. Herein, red-emitting CsPbI QDs are reported with excellent optoelectronic properties and stability based on the synergistic effects of halide-rich modulation passivation and lattice repair.

Tuning the local S coordination environment on Ru single atoms to boost the oxygen evolution reaction.

Engineering the local electronic structure of single atom catalysts (SACs) still remains challenging. In this study, a Ru-NiS single atom catalyst with a controlled S coordination environment, where Ru single atoms are implanted on a NiS nanoflower consisting of plenty of cross-linked nanosheets, has been developed a facile atom capture strategy. Using Density Functional Theory (DFT) calculations, it has been revealed that the fine-tuned local S coordination environment can optimize the electronic structure of Ru active sites, and reduce the energy barrier of the rate-determining step for the oxygen evolution reaction (OER), thus boosting the electrocatalytic activity, such as a low overpotential of 269 mV at 10 mA cm.

Designing Fluorescent Interfaces at Hotspots in a Plasmonic Nanopore for Homologous Optoelectronic Sensing.

In this work, a site-selective functionalization strategy is proposed for modifying fluorescent dyes in the plasmonic nanopore, which highlights building optoelectronic dual-signal sensing interfaces at "hotspots" locations to construct multiparameter detection nanosensor.
